The primary aim of this study is to evaluate the impact of titration, analgesics, and 12 month telephone follow-up period from the B.E.T.A nurse program upon adherence to treatment with Betaseron in patients with a first clinical demyelinating event suggestive of Multiple Sclerosis (MS) and patients with onset of RRMS within the past 12 months

Secondary outcomes include analysis of the following parameters: progression of clinical severity by the expanded disability status scale (EDSS score), health related quality of life (HrQoL), and safety.

Exploratory outcomes include changes over time in cytokine and neurotrophic factor production by immune cells and visual function as assessed by visual examination, OCT measurements and a neuro-ophthalmologic Health-Related Quality of Life questionnaire (NEI-VFQ-25) with 10-item supplement.

Open-Label, Multicenter, Observational, Phase IV Study to Evaluate the Adherence to Treatment With 250mcg (8MIU) IFNB-1b (Betaseron®) Given Subcutaneous Every Other Day Over a Period of up to 12 Months in Patients With a First Clinical Demyelinating Event Suggestive of Multiple Sclerosis and Patients With Onset of Relapsing-Remitting Multiple Sclerosis (RRMS) Within the Past 12 Months
